Two sides.The periphery of steady wheel and the bottom face contact of track, give track bottom surface certain pretightning force, can prevent structure
Frame is turned on one's side.
The utility model has the following beneficial effects:
For the connecting component of this bogie and car body by the way of the traction pin connection being arranged in support plate, replacement is existing
There is the pull rod connection in technology, limits rotational freedom of the car body with respect to bogie, avoid " nodding " and sidewinder phenomenon
Occur；Position-arresting disk in traction pin can effectively prevent car body and bogie to be detached from.The steady wheel and directive wheel of setting are in vehicle
Body collective effect when sidewindering, can limit the displacement of bogie, to prevent bogie from turning on one's side.
This bogie is arranged by the way of setting in single traveling wheel and drive shaft (shaft), makes the structure of bogie more
It is compact；Shaft and motor direct-connected directly control the speed and braking of traveling wheel by the revolving speed and rotation direction of control motor,
The devices such as retarder are eliminated, keep the structure of bogie simpler compact；Support plate passes through this arch knot of curved support arm
Structure supports architecturally, improves support strength and reduces the weight of bogie, bogie is made to become lighter.
Therefore, the bogie structure in this programme is simple, compact and light, and equally can be avoided car body and bogie
" nodding " occurs, sidewinders phenomenon, so the bogie in this programme can be used in small-sized monorail train, can guarantee minitrain
Steadily, it safely runs.

It is contacted to the periphery of wheel 4 with rail-guided face 92, makes this bogie always along rail by the collective effect of two sides directive wheel 4
Road is advanced, and can prevent train from derailing.Directive wheel 4 limits the displacement freedom in level, and steady wheel 5 limits Vertical Square
Upward displacement freedom, under the collective effect of directive wheel 4 and steady wheel 5, this bogie drives train always along rail
Road 9 is run, and ensure that the stability and safety of train operation.
Four curved support arms 61 are welded on the top of framework 1, four curved support arms 61 are successively vertically encircled into one
A rectangle.Curved support arm 61 is bent into semicircle using hollow pipe, and both ends are welded with square block, are existed by direction block welding
On the top surface of framework 1, square block is capable of increasing contact area, extends welding route, to increase the intensity being fixedly connected.
Curved support arm 61 from framework 1 at one end inwardly tilt after be fixed on the bottom surface of support plate 6.Support plate 6
Center for circular slab, top surface is connected with a traction pin 7 by bolt.Traction pin 7 is circular cylinder, in circle
The top of shape cylinder is clamped ON TRAINS integrally formed with the outwardly extending disk of outer diameter, the disk, can be prevented train and be turned
It is detached to frame.
The pressure spring 82 that an outer diameter is slightly less than 6 outer diameter of support plate is placed in support plate 6, in pressure spring 82 and traction pin
At least four dampers 81 are installed on 6 face of support plate between 7, one end of damper 81 is fixed on car body, the other end with
6 top surface of support plate is fixed.Damper 81 is nitrogen shock absorber.
In conclusion the bogie structure in this programme is simple, light, at low cost, small-sized sit-astride list can be applied to
On rail train, and it can effectively prevent between train body and bogie there is a phenomenon where " nodding " and sidewinder, increase column
The stability and safety of vehicle operation.
